【０００１】[0001]

【産業上の利用分野】[Industrial applications]

本考案は、布団，クッション等の詰わたに関する。 The present invention relates to a padded material such as a futon and a cushion.

【０００２】[0002]

【従来の技術】[Prior art]

布団，クッション等の詰わたは、天然繊維，合成繊維等のウェッブを適宜厚さ に折り畳み或いは重ね合わせて所要の厚さにしたものが、一般に用いられている 。これらの詰わたは、天然繊維等の短繊維にあっては、カーディングの後それを 縦方向或いは横方向に折り返しつつ所定厚さに積層し、或いは必要に応じ適宜異 なった種類のわた層を重ね合わせている。また、長繊維わたにあっては複数のト ウを並置しそれを所定幅に拡幅し嵩高処理を行なっていた。 As for the padded material such as futon and cushion, a web of natural fiber, synthetic fiber or the like is appropriately folded or superposed to have a desired thickness, and is generally used. In the case of short fibers such as natural fibers, these stuffed materials are laminated with a predetermined thickness after folding back in the vertical or horizontal direction after carding, or if necessary, different types of cotton layers Are overlaid. In addition, for long fiber cotton, a plurality of tows were juxtaposed and expanded to a predetermined width for bulking.

【０００３】 これらの従来の詰わたは、詰わたを構成する繊維間はあまり縺れ合うことはな く、永年の使用により繊維間がずれ、所謂へたり現象を生ずることがあった。へ たり現象が生じた詰わたはその密度が高くなり、詰わた内の空間領域は減少しわ た内の空気の移動は少なく、湿気の放出が低下し、保温性も低下する。また、使 用感が硬くなるなどの不具合が生じている。[0003] In these conventional clogs, the fibers constituting the clogs do not tend to be entangled with each other, and the fibers may be misaligned due to long-term use, resulting in a so-called sag phenomenon. The clogged with the sagging phenomenon becomes denser, the space area inside the clogged is reduced, the movement of air inside the clog is less, the release of moisture is reduced, and the heat retention is also reduced. There are also problems such as a hard feeling in use.

【０００４】 そこで、上記現象に対処するために詰わたを構成するウェッブを作る際にウェ ッブ構成繊維に接着剤を撤布し、ウェッブ内で互いに接触している繊維の接着点 に接着剤を付着させ、該部を固定する手段が講じられた詰わたがある。しかし、 この手段によると繊維の量が多い場合撤布する接着剤の量を多くしなければなら ず、また、繊維密度が高い場合、繊維間に均等に接着剤を撤布することがむずか しい。しかも、接着点が多過ぎるとわた全体が粗硬となり使用感に劣るという事 態が生ずる。Therefore, in order to deal with the above-mentioned phenomenon, when making a web that constitutes a clog, the adhesive is removed from the fibers constituting the web, and the adhesive is applied to the adhesive points of the fibers that are in contact with each other in the web. There is a clog provided with a means for adhering and fixing the part. However, according to this method, when the amount of fiber is large, the amount of adhesive to be removed must be increased, and when the fiber density is high, it is difficult to remove the adhesive evenly between the fibers. . Moreover, if there are too many adhesion points, the whole cotton will be rough and hard to use and will not be used.

【０００５】[0005]

【考案が解決しようとする課題】[Problems to be solved by the device]

上記の点に鑑みて、詰わたを構成する繊維同士間にずれを生ずることがなく、 繊維間空間の流通を常に良好に保ち得る詰わたを得ることを目的とする。 In view of the above points, it is an object of the present invention to obtain a clog that does not cause a gap between the fibers constituting the clog and can always maintain good flow in the inter-fiber space.

【０００６】[0006]

【課題を解決するための手段】[Means for Solving the Problems]

熱溶融性を有する繊維を含むウェッブよりなり、厚さ方向に複数の小孔を穿孔 し、小孔の周壁面に位置するウェッブ構成繊維の交差部位を融着した。 The web was composed of heat-fusible fibers, and a plurality of small holes were perforated in the thickness direction, and the intersections of the web-constituting fibers located on the peripheral wall surface of the small holes were fused.

【０００７】[0007]

【作用】[Action]

ウェッブを構成する繊維が熱溶融性を有する繊維を含むものであり、該ウェッ ブに厚さ方向に小孔を穿設するときに、穿孔針を加熱しておくことによりそれに 接する小孔の周壁面に位置するウェッブ構成繊維は溶融され穿孔針が引き抜かれ た後、小孔の周壁面を構成する繊維同士の交差部位は互に融着された状態となる 。 The fibers composing the web include fibers having a heat-melting property, and when a small hole is formed in the web in the thickness direction, by heating the piercing needle, the circumference of the small hole in contact with it. After the web-constituting fibers located on the wall surface are melted and the piercing needle is pulled out, the intersections of the fibers forming the peripheral wall surface of the small hole are fused together.

【０００８】 上記小孔周壁面に構成された繊維同志の融着部は詰わた使用中に繊維同士のず れが生ずるのを防止すると共に、小孔は詰わた内部の湿分等を排除する通気路と もなる。そして、ウェッブ構成繊維は前記融着部が存在する小孔周壁以外では固 定されていないので、詰わたが粗硬となることはない。The fusion portion of the fibers formed on the peripheral wall surface of the small hole prevents the fibers from being displaced from each other during use, and the small hole removes moisture and the like inside the closed hole. It also serves as a ventilation path. Since the web constituent fibers are not fixed except for the small hole peripheral wall where the fused portion is present, the clogs do not become coarse and hard.

【実施例】【Example】

本考案の実施の一例を図面と共に次に説明する。 An embodiment of the present invention will be described below with reference to the drawings.

【００１０】 本考案詰わた１は、クッション，布団等に使用される。適宜繊維長にカットさ れた熱溶融性繊維２、或いは天然繊維を適宜含む熱溶融性繊維２をカットしてな るウェッブ３を適宜厚さに積層し（図示の例では３層）その厚さ方向に複数の小 孔４を穿設する。熱溶融性繊維の例としてポリエステル繊維があるが、天然繊維 を適宜含む熱溶融性繊維の場合、天然繊維の比率は熱溶融性繊維の端部が後述す る融着し一体化する部分を作ることの可能な範囲で少なくすることが出来る。小 孔４は、針或いは先端を刃状とした中空管状の穿孔部材５により積層したウェッ ブを突き刺すことにより作られる。小孔４を針で作ったときは直径０．５ｍｍか ら３ｍｍ程度までが得られる。針で小孔を作ったときは、詰わた１を構成する繊 維を切断することは少ないが、１平方ｃｍ当たり３０個所程度までとする。穿孔 部材５を用いたときは小孔の直径を２０ｍｍ程度までとし、小孔の直径及び密度 により詰物の弾性を損なわない程度に詰わたを構成する繊維の密度を変化させる 。The padded 1 according to the present invention is used for a cushion, a futon or the like. The heat-fusible fibers 2 appropriately cut into fiber lengths, or the webs 3 obtained by cutting the heat-fusible fibers 2 including natural fibers as appropriate are laminated to an appropriate thickness (three layers in the illustrated example). A plurality of small holes 4 are formed in the vertical direction. Polyester fiber is an example of heat-fusible fiber, but in the case of heat-fusible fiber containing natural fiber as appropriate, the ratio of natural fiber is such that the end of the heat-fusible fiber is fused and integrated as described later. It can be reduced to the extent possible. The small hole 4 is made by piercing a web laminated by a needle or a hollow tubular perforating member 5 having a blade-like tip. When the small hole 4 is made with a needle, a diameter of 0.5 mm to 3 mm can be obtained. When small holes are made with a needle, the fibers that make up the clogged 1 are rarely cut, but the number is limited to about 30 per square cm. When the perforating member 5 is used, the diameter of the small holes is limited to about 20 mm, and the density of the fibers forming the jam is changed by the diameter and the density of the small holes to the extent that the elasticity of the filling is not impaired.

【００１１】 上記穿孔部材５の支持部材の一例を揚げると、図２に示すように、穿孔部材５ は基板６に複数が適宜配置に植設され、重ねたウェッブ３を挾持する状態に上下 に設けた案内板７，８の案内孔９に案内されている。そして、基板６を上下動す ることによりウェッブ３に穿孔する。上記穿孔時、穿孔部材５は、その基部に設 けた加熱手段１０によりウェッブを構成する熱溶融性繊維２の溶融温度に保たれ ているので、穿孔部材５と接した熱溶融性繊維２は、接触部位が溶融し穿孔部材 ５が上昇しウェッブ３から引き抜かれたときに、ウェッブ３に穿孔された小孔４ の周壁面に位置する熱溶融性繊維の端部同士が互に融着し、一体化部分１１を構 成する。上記穿孔部材５の加熱手段は、穿孔部材５の基部に設けず、針又は筒状 の穿孔部材５の内部に装填されたものでも良い。When one example of the supporting member of the perforating member 5 is lifted, as shown in FIG. 2, a plurality of perforating members 5 are planted in a substrate 6 in an appropriate arrangement, and the perforating members 5 are vertically moved to hold the overlapped webs 3. It is guided in the guide holes 9 of the provided guide plates 7 and 8. Then, by moving the substrate 6 up and down, the web 3 is perforated. During the perforation, the perforating member 5 is kept at the melting temperature of the heat-melting fiber 2 constituting the web by the heating means 10 provided at the base thereof, so that the heat-melting fiber 2 in contact with the perforating member 5 is When the contact part melts and the perforating member 5 rises and is pulled out from the web 3, the ends of the heat-meltable fibers located on the peripheral wall surface of the small hole 4 perforated in the web 3 are fused to each other, The integrated portion 11 is formed. The heating means for the perforating member 5 may not be provided at the base of the perforating member 5 and may be loaded inside the needle or tubular perforating member 5.

【００１２】 上記のようにして構成された小孔４は、詰わた１の内外部を連通して、使用中 に、詰わた１を構成するウェッブ３の内外部の空気を入れ替える作用をし、詰わ た１内部に湿気が溜まるのを防止する作用をする。また、小孔４の周壁面の繊維 が互に融着し合い一体化した部分１１を作るウェッブ３は、ウェッブ３を構成す る繊維に力が加わったとき、外力に対向し繊維間にずれの生ずるのを防ぎ、へた りを防止する作用をすると共に繊維間に移動がないため小孔を塞ぐことがない。 また、ウェッブ３を構成する繊維同士で一体化された部分１１は小孔４の周壁面 の部分だけであり、ウェッブ３全体に広がっているわけではないので、非一体化 部分では繊維が自由状態にあり、詰わたに粗硬感が生ずることはない。The small hole 4 configured as described above communicates the inside and the outside of the clogged 1 and acts to exchange the air inside and outside the web 3 constituting the clogged 1 during use, It works to prevent the accumulation of moisture inside the clogged inside. Further, the web 3 forming the integrated portion 11 in which the fibers on the peripheral wall surface of the small hole 4 are fused and integrated with each other is such that when a force is applied to the fibers forming the web 3, the web 3 opposes an external force and is displaced between the fibers. It prevents the occurrence of swelling, prevents sagging, and does not block the small holes because there is no movement between fibers. Further, the portion 11 in which the fibers constituting the web 3 are integrated with each other is only the portion of the peripheral wall surface of the small hole 4 and does not extend to the entire web 3, so that the fibers are free in the non-integrated portion. Therefore, there is no feeling of coarseness in the jam.

【考案の効果】[Effect of device]

本考案詰わたは、熱溶融性を有する繊維を含むウェッブよりなり、厚さ方向に 複数の小孔を穿孔し、小孔の周壁面に位置するウェッブを構成する繊維の交差部 位を融着してなるために、常に外部から詰わたを構成するウェッブ内部に通ずる 導通孔が存在することになり、使用中に詰わた内部と外部との空気の入れ替えが 行なわれることになり、詰わた内が過湿することが防止されるばかりでなく、小 孔の壁面で融着した一体化部分のため小孔壁面が崩れることなく固定され、それ は同時に詰わたを構成する繊維がずれるのも防止するので永年の使用による詰わ たのへたりを生ずることも防止できる。また、上記一体化部分は小孔の周壁部だ けでありウェッブ全体には及んでいないため、自由状態にある繊維のために詰わ たが粗硬となるのが防止されている。 The pad of the present invention is composed of a web containing heat-fusible fibers. A plurality of small holes are bored in the thickness direction, and the crossing positions of the fibers forming the web located on the peripheral wall surface of the small holes are fused. As a result, there will always be a through-hole that leads to the inside of the web that constitutes the clog from the outside, and air will be exchanged between the inside and the outside that was clogged during use. Not only is it prevented from over-humidifying, but the wall surface of the small holes is fused and integrated so that the wall surface of the small holes is fixed without breaking, and at the same time the fibers that make up the clogs are prevented from shifting. Therefore, it is possible to prevent the occurrence of jams due to clogging due to long-term use. Further, since the above-mentioned integrated portion is only the peripheral wall portion of the small hole and does not extend to the whole web, it is prevented from being clogged by the fibers in the free state but becoming coarse and hard.
